To all whom it may concern:

Be it known that THOMAS DANIEL KELLY, a subject of the King of Great Britain, residing at Hove, Sussex, England, has in- 6 vented certain new and useful Improvements in Cementing Material, of which the following is a specification.

A very tough cementing material which is not brittle and will practically stick any- The setting of the material is accelerated by heat and unlike ordinary cement concrmhs not powder, nor expand, nor contract at high temperatures, in fact after be ing subjected to a temperature of 2000 F. for six hours was found to be perfectly waterproof, as hard as before and no trace of expansion or cracking.

The approximate proportions are as fol- 10 thingfdand ils1 prop: agaiplst extremes 01fl hea, lows 5 or co ,suc as e or 0st, water, 0' an acids, is made by mixing a liquid, insoluble t i ig g :3 ig: in water, but strongly adhesive, such as oxii i 100 to dized or 01 merized oils which are not Fillin "'z' i i"" 500 t 1k easily saponllied W155 wat ls and then g ma 6 0 y u 5 addin h v n ted Port 0; The oxi- What I do claim as my invention, and dedized or p0 y may be Chinese wood or tun oil crude mineral 6mm, and other analogous oils.

To this mixture while plastic, any aggregate or filling material which is not of a greasy or oily nature, is added and the whole compressed in molds of the desired shape, or if used in large areas, compressed in situ by means of rollers and leveled and faced by sliding irons as used for ordinary asphalt. Oils which are not adhesive should not be used as they detract from the stren h.

The material while plastic is rein orced in addition to or instead of compressing with iron or steel bars, plates, strips, wire or like strengthening materials.

In the case of large areas such reinforcement is added before facing and leveling.

side to secure by Letters Patent, is:-

1. The improved fireproof, wa erproof, and acid proof cementing material made by mixin water glass with an adhesive li uid insolu le in water, and not easily saponi ed, and hydrated Portland cement.

2. The improved fireproof, waterproof, and acid proof material, made b mixing water glass with an adhesive liquid insoluble in water, and not easily saponified, and hydrated Portland cement and a suitable filling material.
